No. Round-ups come from any payment your Centurion wallets make, whatever app you use and whichever of the 10 chains it is on. Trade on Hyperliquid, Polymarket, Uniswap or anywhere else exactly as you do now.

10: Robinhood Chain, Ethereum, Base, Arbitrum, HyperEVM, Polygon, BNB Chain, Avalanche, Monad, Arc. Your wallets are the same address on all of them, so there is nothing to enroll per chain. Spare change from every one of them lands in the same pot on Robinhood Chain.

Yes, because both are dollars leaving your own wallet: a Hyperliquid deposit is USDC going to the bridge on Arbitrum or HyperEVM, and topping up Polymarket is USDC leaving your wallet on Polygon. What does not round up is anything that leaves somewhere else — the perp fills inside Hyperliquid happen off the EVM, and each Polymarket bet is signed from their per-user proxy rather than from the address you enrolled.

No. An Ethereum address is the same address on every EVM chain. Enroll a wallet once and its payments on all of the chains round up into the same pot.

A token on Robinhood Chain that tracks a stock's price. It is not a real share: no ownership, no voting rights.

Your spare change is invested once it reaches the threshold you set in Setup, $10 by default. You can raise it; it cannot go below $10. Small amounts wait until they add up.

Yes, any time from the Portfolio page. No fee.

That is the normal case. Round-ups are taken from the wallet's ETH (or BNB, AVAX, POL on those chains) and converted within 1% of the Chainlink price. Nothing to approve, nothing to park. On chains whose coin has no USD feed yet, USDC pays instead.

Your wallets are Centurion wallets, held by Privy. At sign-in you grant Centurion a signer that can only call our contracts, under a cap. That is what pays a round-up out of your wallet after a trade anywhere, on any chain. Turn it off in Setup and it stops everywhere.

Yes. Import it on the Wallets page by pasting its private key. The key goes to Privy, not to us, and the address does not change. From then on its trades on every chain round up into the same pot as your other wallets.

Any time. Export the private key from the Wallets page and use it in MetaMask, Rabby or anywhere else. Your tokens are on the address, not with us.

Any token on Robinhood Chain: ETH, memecoins, Stock Tokens. Paste a contract address in the token picker if it is not listed. If it has a pool, it trades.

A round-up is paid from what the wallet holds at that moment. Holds less than the round-up: we take what is there. Holds nothing usable: that round-up is skipped, and the next payment starts fresh. Nothing waits for a top-up.

Switch Round-ups off in Setup. Nothing more is taken from your wallets after that.

We do: setup, every round-up on every chain, and every purchase. The only gas you pay is on trades you place yourself.

5% of each round-up, so about 3 cents on a $0.65 round-up. No subscription. Swaps on the Trade page also show a small app fee in the quote (0.20% by default).

Half runs Centurion. Half buys and burns CENT.

0.5% of CENT trading volume fills a daily pool. It is split between accounts that paid fees that day, by how much each paid.

No. Everything works the same either way.

Update your allocation in Setup and save. It applies to your next purchase.

Change your allocation to drop it. What you already own stays in your wallet.

Yes. The Trade page swaps any token for any other, paid in ETH or whatever you hold, and rounds up the trade itself in the same transaction. Trades made elsewhere from your Centurion wallets round up too.

No. They go straight to your wallet. Hold, transfer, or sell them whenever you want.

Your Stock Tokens are in your wallet and tradable anywhere. Uninvested funds stay withdrawable, and you can export every wallet's key.

No. The signer you grant can only call our contracts, under a cap: round-ups into your own pot, purchases of stocks you picked, and the trades, deposits, withdrawals and reward claims you ask for. There is no admin switch that can drain your funds.

Every contract is source-verified on the block explorer, so you can read the deployed code yourself.

A stock needs a Chainlink price feed and a liquid pool before we can trade it safely. The ones without both are listed but not yet tradable.

Boost adds 1%, 2%, 5% or 10% of every transaction on top of the round-up. It is off by default.

We read priced payments leaving that address on the chains we can reach and apply the same round-up math. It is an estimate at today's prices, not a promise that those round-ups were captured.

One round-up a day keeps your streak going. You can share a card of it without showing your wallet address.

Yes. Import any wallet from the Wallets page by pasting its private key. All your wallets pay into one pot and buy the same stocks, and you can export any key to use it elsewhere.
